No, I'm not sure. It might not be bluetooth-related, but perhaps is
caused by the mixer settings. I don't hear my own echo when talking
without the bluetooth headset though.

Yes, and maybe the metallic sound is possible to fix with this as well.
I've tried changing mixer settings in alsamixer somewhat at random
(basically turning all knobs), but wihtout getting any real
improvement. Anyway, I'm sure it's possible to get this working some
way and at least for me it would be a huge usability improvement of the
phone.
